Manage layout when keyboard is visible

Software keyboard takes almost half of the screen. If you have interactive elements that can get covered by the keyboard, make sure they are still accessible by using the KeyboardAvoidingView component.

Make tappable areas larger

On mobile phones it's hard to be very precise when pressing buttons. Make sure all interactive elements are 44x44 or larger. One way to do this is to leave enough space for the element, padding, minWidth and minHeight style values can be useful for that. Alternatively, you can use hitSlop prop to increase interactive area without affecting the layout. Here's a demo:

Use Android Ripple

Android API 21+ uses the material design ripple to provide user with feedback when they touch an interactable area on the screen. React Native exposes this through the TouchableNativeFeedback component. Using this touchable effect instead of opacity or highlight will often make your app feel much more fitting on the platform. That said, you need to be careful when using it because it doesn't work on iOS or on Android API < 21, so you will need to fallback to using one of the other Touchable components on iOS. You can use a library like react-native-platform-touchable to handle the platform differences for you.

Screen orientation lock

Multiple screen orientations should work fine by default unless you're using Dimensions API and don't handle orientation changes. If you don't want to support multiple screen orientations, you can lock the screen orientation to either portrait or landscape.

On iOS, in the General tab and Deployment Info section of Xcode enable the Device Orientation you want to support (ensure you have selected iPhone from the Devices menu when making the changes). For Android, open the AndroidManifest.xml file and within the activity element add 'android:screenOrientation="portrait"' to lock to portrait or 'android:screenOrientation="landscape"' to lock to landscape.
